-->'''WALTER:''' Please, don't tell him.

* WhamEpisode: Olivia realizes Peter is from the Other Side.

* WhamEpisode: Olivia realizes Peter is from the Other Side

** When Olivia is given Cortexiphan, she says she is SinginInTheRain.

** Why the 35 hour window? The law of of conservation of energy demands instantaneous payment and doesn't take [=IOUs=], as far as our universe's laws of physics work.
*** Because the energy required for the transfer takes that amount of time. Transporting matter from one universe to another requires massive amounts of energy. It's also another foreshadowing to how the laws of physics in both universes are becoming unstable.
** When Walter took Peter from the alternate universe, did another child of the same mass disappear from our universe? And what about when Olivia or Wlliam Bell went to the alternate universe?
*** Maybe not. The EquivalentExchange seems to apply only when using a certain method of interdimensional travel or teleportation. Walternate states that every method the Red Universe has of crossing to the Blue Universe has its own risks and consequences; Walter's machine didn't cause anyone to vanish, but it shattered the laws of physics, causing quantum decay on the Red Universe. Likewise, Bell's method of transportation [[spoiler: made his molecules unstable, making him a walking time bomb]], while the method used by Walternate left him bedridden for quite a while. And the "Tuning Fork Beacon" method utilized by Walter and Newton in this episode has the EquivalentExchange issue. Olivia's use of Cortexiphan is the only one that doesn't have any consequences when used correctly.

In Manhattan, a building from the alternate universe is transported into the prime universe, merging with its counterpart with catastrophic consequences for everyone inside: one man finds himself fused together with his counterpart and somehow still alive despite suddenly having too many limbs and organs. As Olivia investigates and learns that Newton is responsible, Walter theorises that due to the method used to cross one building over to the other side -- based on the original methods used in Walter and William Bell's earliest experiments in which objects of equal mass in both universes swap places -- a building from the prime universe Manhattan will disappear into the alternate universe with the space of a day or so.

To identify the building that will disappear and save the people inside, Walter suggests that he and Olivia revisit the cortexiphan experiments from over twenty years ago, they travel to small daycare in Jacksonville Florida. The cortexiphan, which had allowed her to identify objects from the other side (by their "glimmer") and even travel between the two universes. Since the ability was dormant, Walter tries to reawaken it with a fresh dose of cortexiphan. The ability is subsequently triggered by Olivia's emotions, specifically fear, but the result of a lifetime's worth of physical, mental and emotional abuse has caused her psyche to harden to the point of being fearless. Considering the experiment a failure, the Fringe team return to New York and work with Massive Dynamic to try and identify the building using other means, such as identifying a building with the exact same mass as the one that appeared from the other universe.

As the expected time of the building's disappearance draws closer, Olivia becomes increasingly guilty over the failure of the cortexiphan experiment and afraid for the people she's unable to save -- which triggers the ability and allows her see the "glimmer" of the other side and identify the building. The FBI evacuates just in time, so that there are no casualties when the building disappears. Later, Olivia goes to the Bishops' house, planning on going out for celebratory drinks with Peter. When she sees the glimmer around Peter, she realises that he's from the alternate universe. Walter begs her not to tell Peter.

* DifferentWorldDifferentMovies: Mammoth toy figures from the IceAge movie which aired in 2002 are seen in the classroom that is supposed to have been locked up since 1985, suggesting these items were from the Alternate Universe and this movie occurred much earlier in the other universe's timeline.

* BloodOnTheseHands: A literal example where Walter is wearing blood stained latex gloves while holding the phone may [[{{Foreshadowing}} foreshadow]] Walter's guilt for the events causing the clash of the universes.
